To insist on choosing the name for baby

[goldenflowers95]

I was in a long term relationship that resulted in a pregnancy, dp at the time stated he wasn't ready for a child and wanted me to have an abortion - I didn't, so the relationship ended. He then blocked me and didn't speak to me for months. In that time I found out I was expecting a girl and picked out a name for her. Ex dp has now decided he wants to be involved after all and doesn't like the name I have chosen. I said I'm not changing it because I was under the impression he wouldn't be involved and chose her name when he wasn't around. He says it's not fair and he should have a say in the name now that he's going to be involved. I'm quite annoyed because I love the name I've chosen and can't see myself naming her anything else! AIBU?

I agree with previous poster that everyone has the right to know the identity of their biological parents but nowadays when so-called illegitimacy no longer has a stigma this knowledge is only a secret if the adults choose to keep it and this OP is clearly not in this category.
OP you need to protect yourself and the wellbeing of your DD in every way you can. You only have to read some of the threads here to learn how fathers often use their children to manipulate their ex partners

it costs a lot of time and money for a man to fight for thier parental rights in court even if they are on the birth certificate and mum is refusing access to the child. I know a man who had to fight to see his child and he's still in debt now after only being given every other weekend at the end of the whole process.

EOW is generally in the best interests of the child. We aren't sharing out sweets.
